3600*1700*1850mm Specification DAF System with 0.1kw Skimmer and 0.55kw Coagulate Agitator for Water Treatment

Dissolved Air Flotation (DAF) is an advanced water treatment process designed to clarify wastewater by effectively removing suspended matter such as oil and solids.

The process involves dissolving air in water under pressure, then releasing it at atmospheric pressure in a flotation tank. This creates microbubbles that adhere to suspended particles, causing them to float to the surface where they can be removed by skimming.

1. Wastewater enters RT1 (coagulation reaction tank) and RT2 (flocculation reaction tank) from the equalization tank through the lift pump, where it coagulates with PAC and flocculates with PAM to form flocs.

2. The wastewater and dissolved water then enter the reaction zone of the DAF tank, where microbubbles adhere to flocs to form solid particles with density less than water.

3. These particles float to the surface and are scraped into the slag tank, while clean water is collected below and either discharged or recirculated.

• Microbubble generation for efficient particle removal
• Subsurface capture technology
• Automatic slagging controlled by liquid level
• Non-clogging release mechanism with high efficiency

Consider these factors when selecting a DAF system:

• Wastewater type (dairy, car washing, slaughter house, food processing, etc.)
• Suspended solids content (ppm or mg/L)
• Oil, grease, fat content (ppm or mg/L)
• pH level (6-9 preferred; corrosive substances may require special materials)
• BOD and COD levels (ppm or mg/L)
